Shingles is a disease caused by the varicella-zoster virus, which is the same virus that causes chickenpox. After chickenpox illness, the virus lies dormant in certain nerve tissue. As people age, it is possible for the virus to reappear in the form of shingles. Shingles is more common in people 50 years of age and older and in people who have weak immune systems. Up to 1 million cases of shingles occur each year in the United States.
A shingles rash usually appears on one side of the face or body and follows along the nerve root. The rash lasts from 2 to 4 weeks. The main symptom of shingles is pain, which can be quite severe and persist even after the rash is gone. Other symptoms include fever, headache, chills and upset stomach.
Treatment of shingles focuses on shortening the length of illness and pain relief. Antiviral medications, such as acyclovir, famciclovir, and valacyclovir, are used to help shorten the length of illness. Pain medications, including topical medications, are used to help relieve the pain associated with shingles.
There is only one shingles vaccine. It is a live, attenuated vaccine.
